Summary

Lichenoid drug eruptions are rare adverse effects of statin medications. This case study details a patient who experienced a recurring lichenoid eruption linked to pravastatin therapy.

Background:

Drug eruptions are known adverse reactions to various medications, including statins.
Lichenoid eruptions, a specific type of skin reaction, are infrequently reported with statin use.

Observation:

A patient developed characteristic lichenoid lesions after starting pravastatin.
The skin lesions resolved upon discontinuation of pravastatin.
The lichenoid eruption recurred when the patient was rechallenged with pravastatin.

Findings:

This case highlights a rare instance of a lichenoid drug eruption associated with pravastatin.
The temporal relationship between pravastatin use and the eruption suggests a causal link.
Rechallenge confirmed pravastatin as the likely causative agent.

Implications:

Clinicians should consider pravastatin as a potential cause of lichenoid eruptions in patients presenting with these lesions.
This report contributes to the understanding of rare adverse skin reactions associated with 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors.
Further investigation into the mechanisms of statin-induced lichenoid drug eruptions may be warranted.
